Dispelling the Anthropic Principle from the Dimensionality Arguments

TL;DR

This paper demonstrates that in 11-dimensional supergravity, a reasonable assumption leads to a 4-dimensional universe without relying on the Anthropic Principle, challenging its necessity in cosmological explanations.

Contribution

It provides a theoretical argument that naturally results in a 4-dimensional spacetime from supergravity, reducing dependence on the Anthropic Principle.

Findings

Nearly flat spacetime in 11D supergravity implies 4D universe

The result does not require Anthropic Principle assumptions

Supports intrinsic dimensionality from fundamental physics

Abstract

It is shown that in d=11 supergravity, under a very reasonable ansatz, the nearly flat spacetime in which we are living must be 4-dimensional without appealing to the Anthropic Principle. Can we dispel the Anthropic Principle completely from cosmology?
